Definitions
- This device has the disadvantage of not providing precise proportioning of the chemical additive. This is party due to the partial mixing of feed water with the chemical additive in the cartridge and partly due to the inherent time-lag in the system caused by canister back-flow after periods of system inactivity. In addition, because the chemical concentration is determined by the restricter orifice, restricters must be experimented with during initial setup to obtain an acceptable initial flow rate.
- the apparatus also includes a quarter turn latching mechanism which facilitates ready replacement of the canister.
- the mechanism includes a spring loaded latch that slideably extends through a portion of the head body and protrudes down past the bottom surface of the body.
- a keyed attachment plate is secured to the bottom surface of the head body to retain the spring and latch.
- the keyed attachment plate includes a keyed aperture having two mating notches.
- Two attachment tabs are attached to the axial connector portion and a pair of latching grooves are formed into the top surface of the canister.
- the canister is removeably attached to the head body by first aligning the attachment tabs with the mating notches of the keyed aperture and passing the connector portion up into the head. Once the connector portion is seated in the head. the canister is rotated one-quarter turn. The canister is locked in place when the latch aligns with and extends into one of the latching grooves.
- a latch 76 which forms part of a quarter turn latching mechanism that slideably extends through an upper surface portion of the body 11 and protrudes down past the bottom surface of the body to facilitate the attachment of the detachable canister 34 to the head body 11.
- the latch is biased downward by a latch spring (not shown).
- a keyed attachment plate 88 Secured to the bottom surface and within the recess of the body 11 is a keyed attachment plate 88.
- the plate 88 which includes a keyed aperture 98, retains the latch 76 and latch spring to the head body 11.
- liquid additive 90 is dispensed into a fluid system in the following manner. Fluid flows from the inlet tube 48, through the first fluid passageway 56 of the manifold 72, and into the inlet portion 14 of the head body 11. The fluid then passes through the radially extending apertures 94 in the side wall of the axial connector portion 63 into the interior region 26 of the detachable canister 34. Fluid then travels through the plurality of axially extending apertures 96 in the top wall of the axial connector portion 63 and into the outlet portion 16 of the body 11. As will be described below, it is at this point where the liquid additive 90 is introduced into the fluid flow.
